This species is found at altitudes of under 1,000 m in the southern Atlantic Forest of Brazil; in Rio Grande do Sul State and southern Santa Catarina State, north to the west side of the Serra Geral mountains.

This species is restricted to the Atlantic Forest. It presumably reproduces by larval development in backwaters of streams and in temporary pools. The species is believed to be fairly tolerant of habitat modification.

The Atlantic Forest has been subject to substantial deforestation and fragmentation due to historical logging and ongoing large-scale clearance for cattle pasture, and crops such as sugar cane, coffee, and exotic trees, as well as for smallholder agriculture. Clearance of forest for coastal development is another threat within the range of this species.
